Toxicity characteristic leaching procedure (TCLP) is a soil sample extraction method for chemical analysis employed as an analytical method to simulate leaching through a landfill. The testing methodology is used to determine if a waste is characteristically hazardous, i.e., classified as one of the "D" listed wastes by the U.S. Environmental ...
The United States Environmental Protection Agency (EPA) maintains and approves test methods, which are approved procedures for measuring the presence and concentration of physical, chemical and biological contaminants; evaluating properties, such as toxic properties, of chemical substances; or measuring the effects of substances under various conditions.
This method was developed in the early 20th century by George de Hevesy for which he was awarded the Nobel Prize in Chemistry for 1943. An early application of isotope dilution in the form of radiotracer method was determination of the solubility of lead sulphide and lead chromate in 1913 by George de Hevesy and Friedrich Adolf Paneth.

The United States Environmental Protection Agency (EPA) issues Effluent Guideline regulations for categories of industrial sources of water pollution under Title III of the Clean Water Act (CWA). [1] The standards are technology-based, i.e. they are based on the performance of treatment and control technologies (e.g., Best Available Technology ...
An Argentinian waiter prosecutors are looking to charge in connection with One Direction star Liam Payne's death admitted to using cocaine with the singer — but insists he was not the drug dealer.
An MTA cleaner allegedly slashed a man who confronted him for pouring bleach near the spot where he’d been sleeping on a Brooklyn subway platform early Monday, cops and sources said.
Non-MS methods using GCs and LCs having universal or specific detectors are still staples in the arsenal of available analytical tools. Other parameters often measured in environmental chemistry are radiochemicals. These are pollutants which emit radioactive materials, such as alpha and beta particles, posing danger to human health and the ...
The New York City Ballet has been performing "The Nutcracker" for decades. Each year, young dancers make their mark on the ballet.
